Title: Improvements in the manufacture of artificial filaments and similar products
IPC: D01F1/10
Filed: 1931-09-11
Abstract: Artificial silks, horsehair, &c. are delustred and improved in their covering properties by incorporating therein a finely divided oxide of antimony.  In addition to being delustred, yarns so treated knit more closely and weave better.  The finely divided antimony oxide may be added to the spinning solution, or the threads &c. may be treated with a suspension or dispersion of the oxide preferably in the presence of a swelling agent for the cellulosic material of which the threads are composed.  The oxide is preferably used in very fine form, for example, with particles of 0,1-5 microns; and the dispersion of the oxide may be assisted by the addition of dispersing agents or protective colloids such as turkey red oil, oleic acid, linseed or olive oil, diethylene glycol, heavy mineral oil or castor oil, either before or after the grinding of the oxide or to the spinning solution. The method is applicable to threads &c. made from viscose, cuprammonia cellulose and nitrocellulose, or from cellulose acetate and other organic esters, or from cellulose ethers.

Filed: 1974-06-10
Abstract: 1479717 Secret signalling PATELHOLD PATENTVERWERTUNGS & ELEKTROHOLDING AG 10 June 1974 [12 June 1973] 25576/74 Heading H4R In a method and apparatus for the secret transmission of speech signals by coding in the transmitter and decoding at the receiver gaps due to pauses are at least partially filled after the encoding stage by the addition of encoded filler signals and are subsequently suppressed in the receiver. The filler signals may fill the gaps or may do so jointly with encoded control signals indicative of the respective gaps. The filler signals encoded from a noise generator may be applied by way of relay contacts and may be placed relative to the speech signals by appropriate delay networks or by the use of appropriate relay holding times. The filling may be achieved by re-reading the contents of a circulating store. The filling may be controlled by a speech detector or by a manually operated button and corresponding control signals delayed as necessary to compensate for delay in other units may be sent over a separate line or as part of a composite signal to achieve synchronization. The filler signal should have a spectrum also encountered in the encoded speech signal. Coding methods exemplified include varying the amplitude of samples, scrambling partial frequency bands and time transposing message portions. The encoded control signals may be encoded by irregular polarity reversals or may comprise keyed tones in a frequency gap in the encoded speech. The onset and termination of speech, may be transmitted by pulse trains in the gaps.

Abstract: 1,182,878. Coated sheet material. FIBER INDUSTRIES Inc. 29 May, 1968 [8 June, 1967], No. 25772/68. Heading B2E. A coated sheet material is produced by coating a flexible substrate with a liquid mixture of a partially polymerised polyurethane elastomer and a solvent in a wet thickness of 10 to 60 mils., removing a major proportion of the solvent from the polyurethane, applying a release sheet over the applied coating to produce a laminate, passing the laminate prior to final cure through a compression zone, applying a pressure of about 25 to 150 lbs. per linear inch of nip onto the laminate, removing the residual solvent, further curing the polyurethane to a hardened tack free state and subsequently removing the applied release sheet from the surface of the polyurethane. The flexible substrate may be a non-woven fabric and may be comprised of a mixture of polypropylene and polyester staple fibres. The release sheet may be an embossing die to produce a deep-embossing. The substrate material may be a water-vapour permeable non-woven needle punched fabric and the laminate is inverted to place the non-woven substrate uppermost after subjecting the laminate to the composition zone and effecting the further volatilization of the solvent and curing of the polyurethane in the inverted position. The pressure may be applied in the compression zone by passing the laminate through a calender. The solvent may be a mixture of a l¾w boiling solvent e.g. methylethyl ketone, and a higher boiling solvent. The solvent may be substantially removed prior to the compression to produce a surface Durometer A hardness of 20 to 80. The polyurethane may contain solid, finelydivided particles which are removed, if desired prior to the removal of the release sheet, from the polyurethane coating to render it porous thereby producing a poromeric material. The substrate may be woven, knitted, braided, twisted, non-woven and may be of animal, vegetable or mineral fibres or mixtures thereof e.g. of cotton, flax, jute, silk, wool, asbestos, nylon, rayon, acetate, triacetate, polyester, polyamide, polyethylene, polypropylene, polyurethane, acrylics, polyvinyl, and cellulose based substrates. The substrates may be bonded with a resinous material e.g. polyester, polyurethane, butyl rubber, melamine formaldehyde resin. The fibrous materials may be laminated with other fibrous materials or with a synthetic plastic sheet material. The composition may be applied by spraying, brushing, spreading, floating knife, calendering, cast coating, or roller coating.

Title: Laminated article and method of producing the same
IPC: B32B27/00
Filed: 1959-07-28
Abstract: At least a portion of a blank of polymerised synthetic resin material and pre-selected configuration is softened by subjecting it to the vapour of a suitable solvent without causing it to become tacky and then supported within a mould of shape conforming to that of the final article, after which a sufficient quantity of flowable synthetic resin substance to fill the mould is introduced, which substance is characterised by bonding to the blank to produce the required laminated article.  The process may be used for producing articles having an inlay of differing colour and less area than at least one major face of the article and lying flush with such face, in particular for spectacle frames in which the upper and lower portions are of different colours or shades.  Suitable synthetic resins for use in the process include cellulose acetate-butyrate and cellulose acetate-propionate. Although it is not necessary that the blank and moulding substance be of the same type of synthetic resin, they should be compatible in order to assure firm bonding.
